Genes affected

TRAM2 (HGNC:16855): (translocation associated membrane protein 2) TRAM2 is a component of the translocon, a gated macromolecular channel that controls the posttranslational processing of nascent secretory and membrane proteins at the endoplasmic reticulum (ER) membrane.[supplied by OMIM, Jul 2004]

Ambry Genetics

Dec 11, 2023

The c.68C>T (p.A23V) alteration is located in exon 1 (coding exon 1) of the TRAM2 gene. This alteration results from a C to T substitution at nucleotide position 68, causing the alanine (A) at amino acid position 23 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
